概要	Comparative document analysis is a qualitative research design that systematically examines two or more documents — or document sets — side by side to identify similarities, differences, patterns, and contradictions across contexts, institutions, time periods, or jurisdictions. Drawing on document analysis as a primary method, the comparative dimension adds analytical leverage by allowing the researcher to ask not just what a document says, but how and why it differs from comparable documents elsewhere.	Critical document analysis is a qualitative method that systematically examines written, visual, or digital documents — such as policy texts, institutional reports, curriculum materials, and official records — through a critical theoretical lens. Rather than treating documents as neutral containers of information, it interrogates how documents produce, reflect, and reproduce power relations, ideologies, and social inequalities. The approach draws on critical theory traditions, including the work of Paulo Freire and Jurgen Habermas, as well as established frameworks for document analysis developed by Bowen and Prior.
